RXPE Static Var Compensator (SVC)

A Static Var Compensator (SVC) is a fast-acting power electronic device used for dynamic control of voltage in a local area or at an interface point. 

Our parent company has more than 50 years’ experience developing reactive power solutions for applications involving fast changing loads. We design, supply, install and commission SVC systems for sectors including power transmission, fusion energy and energy-intensive industry. 

Today, we have the world’s largest installed base of SVCs. Our success is rooted in advanced system capability combined with high-integrity wraparound engineering support.

Technical details

SVCs are part of the Flexible AC Transmission System (FACTS) genre of equipment. They provide variable inductive and capacitive reactive power using a combination of thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC). These are connected to the AC network using a compensator transformer or via a transformer tertiary winding.

An SVC can provide a continuously variable reactive power range using TCRs, with coarser reactive control provided by TSRs and TSCs. The reactive power (MVAr) output of the SVC can be configured for direct or automatic voltage control.

Technical parameters
